My invention relates to envelop fasteners,

and has for its object the provision of cheap and strong means easilyattachable to the outside of any envelop, for holding the flap to thebody of the envelop.

To attain this object, I- employ the devices shown in their preferredforms in the accompanying drawings, in which,

Figure 1 is a view'of an envelop to which my improved fastener isattached showing the flap open. Fig. 2 is a similar view showing theflap closed and heldby the fastener. Fig. 3 .is a view of the metallicpart of the fastener showing one-form of the blank from which saidmetallic part is made. Fig. 4 is a view of a series of fasteners as theyappear before they have been separated.

. eyelet may be substituted for the projections v7, 13 or 14. To attachthe metallic members Figs.'5, 6 and 7 are views of modified forms inwhich the metallic part of the fastener may be made showing variouskinds of attaching means. Fig. 8 is a vertical section on the line A Bof Fig. l, in which the thickness of the parts sectioned are greatlyexaggerated for clearness and Fig. 9 is a bottom viewof the :under sideof the strip of paper to which the fastener is attached, showing thelayer of gum on said strip.

The metallic member 1 is. preferably of the shape shown in Figs. 8 andt, having side prongs of the usu'al'form and pointed projections 7 forattachment to a strip of paper 8 ,said strip 8 having a layer of gum 16on the under side thereof. In place of the pointed rectangularprojections 7, outs I may be made in metallic members as 10 and 12 toform triangular projections as 13 and 14 (Figs. 5 and 6). A circularprojection as 15 in member 11, similar to the ordinary as "1,10, 11 and12 to the gumrned paper 8,

suitable projections as shown and described above are first made in saidmembers, said pro ections then being passed through the paper 8 and bentto suitably engage the ffilnder side of said paper 8 as shown in Fig.

8, and by the dotted lines in Figs.- 1 and 4:.

- The arrangement of a strip of gummed paper 8 with metallic members 1attached thereto at regular intervals (Fig. l) is a convenient method ofmaking the fasteners stream canoe.

when they afe required in bulk, since the paper 8 may be separated intoparts 6 by cutting at regular intervals as on dotted line 9 by asuitable machine and readily set on the outside of an envelop. The paper8' is preferably quite heavyin comparisonwith the paper of the envelopto enable projections 7, 13, 14 "and 15 to firmly grip said paperwithout danger of tearing.

It has heretofore been necessary to open the envelop to attach afastener, and it has also been necessary to use a rather heavy proections suiiicient grip on the'paper. It

is obvious that the envelop need not beopened to attach my fasteneras itis set of the fastener is entirely independentof the thickness or weightof the envelop paper.

.For' strengthening the flap 3 of envelop 2,

the piece 4: of heavy paper may be fastened to said fiap 3, the hole 5then being. punched to allow the prongs of fastener l to pass throughand be bent over as shown in Fig.' 2, to ihold said fiap. r a 35 It isobvious that changes in the form of the metallic member, in the mannerof fastening said member to the paper 8, such as the use of variousforms of prongs and eyelets, and in the shape of the portion 6,

may be made without departing from the scope of my invention.
